A technician is tasked with creating servers that are fault tolerant and highly available.
Which of the following would be the BEST solution for this task?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
To create fault-tolerant and highly available servers, the BEST solution is Clustering (Option C).
Clustering is a technique in which multiple servers are interconnected in such a way that they act as a single logical unit to provide high availability and fault tolerance. The servers in the cluster are aware of each other and work together to distribute the workload and ensure that if one server fails, another takes over automatically without any downtime or interruption to the service.
Load balancing (Option A) is a technique used to distribute workload among multiple servers to prevent overloading of a single server. Load balancing is often used in conjunction with clustering to distribute workload across multiple servers in the cluster.
Virtualization (Option B) is a technique used to create multiple virtual instances of a single physical server. Virtualization provides a high degree of flexibility and scalability but does not inherently provide fault tolerance or high availability.
Round-robin (Option D) is a simple load balancing technique that distributes workload in a rotating manner among a group of servers. Round-robin is not a fault-tolerant or highly available solution and can result in downtime if one server fails.
In summary, Clustering is the best solution for creating fault-tolerant and highly available servers as it provides a comprehensive approach to ensuring service availability and continuity in the event of hardware or software failures.
